Cloud Point Process Analyzer CPA-4

Application

The BARTEC BENKE Cloud Point Process Analyzer (CPA-4) is a system for the fully automaticdetermination of the cloud point (CP) of transparent mineral oil products. The CPA-4operates online. It serves to monitor/maintain product quality for the in-spec productionof mixtures such as diesel fuel and heating oil.

Norms and Standards

ASTM D 2500

DIN EN 23015

ISO 3015

IP 219

These norms and standards set theoperat ing l imits for cloud pointmeasurement for mineral oil products whichare clear at a path length of 40 mm (for IPand ASTM 1 ½ " = 38 mm) and have a cloudpoint below 49 °C (120 °F).

Method

The product sample is cooled under specified conditionsand its turbidity is observed. The temperature at which acloud of paraffin crystals first appears, is measured asthe CP. The CPA-4 uses a photometric measurementprinciple.

Note: Illustrations of this brochure show a typical CPA-4Analyzer with the optional application specific chiller.
